Amazon ECS service discovery makes it easy for your containerized services to discover and connect with each other. Amazon ECS creates and manages a registry of service names using the Route53 Auto Naming API so you can refer to a service by name in your code and write DNS queries to have the service name resolve to the service’s endpoint at runtime.

Service discovery is available for all networking modes for EC2 launch type or with AWS Fargate.
